When disaster hits, preparation is key to preventing poor performance. As Benjamin Franklin famously said, "An ounce of prevention is worth a pound of cure," and this adage rings particularly true when it comes to disaster recovery. Most companies with a decent-sized IT department will have an incident response plan in place, but this is only the starting point.
In reality, such plans need to be constantly updated and tested regularly – and not just by the internal team. Operators also require remediation software and backups ready to roll. Rick Vanover, VP of product strategy at disaster recovery specialist Veeam, admits that his company used to rely solely on tabletop exercises discussing "what if" scenarios as a form of testing. However, this approach proved inadequate in reality.
Over the last few decades, things have changed a lot, and it's essential for companies to adapt their approaches. According to Vanover, practice is still crucial – but not just limited to tabletop exercises. Companies need to actually try out their plans on their own networks or virtual versions of them. This can be achieved through the use of specialized software designed specifically for testing disaster recovery scenarios.
One such tool is Chaos Monkey, developed by Netflix in 2011. Initially designed to randomly shut down virtual machines and cause network problems, the tool has since evolved into a suite of tools dubbed the Simian Army. These include Chaos Gorilla, which mocks an entire AWS availability zone, and Chaos Kong, which simulates bringing down a whole region.
Other companies have also developed their own disaster recovery testing tools. For instance, manufacturers such as AWS offer its Fault Injection Service, while Azure provides Chaos Studio. Open-source code like Litmus for testing Kubernetes resilience is another option, alongside commercial packages like Gremlin.
While software can be an invaluable resource in this process, it's not the only solution. Experts emphasize the importance of human knowledge and experience in disaster recovery planning. Jacob Dorval, senior director at Secureworks Adversary Group, agrees that training and practice are essential for IT staff to develop a deeper understanding of their network.
"I can relate to it so much because of my military experience," he says. "You practice, practice, practice, and you train, train, train. Because when that one time happens, you're like, 'Right? I got this. It's no problem. We know exactly what we're going to do'."
Knowing your network is also vital for successful disaster recovery planning. According to Dorval, constantly updating network mapping is key to detecting problems as they occur and fixing them.
"You've got to make sure you have visibility," he warns. "Because this entire game is all about detection and response. How quick can you detect the threat and then respond to the threat and neutralize the threat? And dwell times are getting shorter and shorter, so making sure that you have visibility is absolutely critical."
For many companies, disaster recovery planning has become a daunting task due to their complex infrastructure. In some cases, even basic tasks such as backing up the Recycle Bin or taking care when using `rm` commands can lead to errors.
In conclusion, disaster recovery is an ongoing process that requires constant attention and practice. Companies must adopt a proactive approach to ensure they are prepared for any disaster that may strike. By utilizing specialized software, training their staff, and regularly testing their plans, companies can minimize the risk of poor performance in the event of a disaster.
